FIELD OF INTEREST

The present inventive concepts relate to the field of personal comfort devices and, more particularly, to personal devices for controlling the temperature comfort of a user.

BACKGROUND

There are many circumstances in which a person (or pet) is in an uncomfortable environment. Various apparatuses have been developed to either warm or cool an individual to achieve personal comfort. For example, handheld personal fans can be used to cool an individual, while handwarmers and pocket warmers have been used to warm an individual. Handheld fans can be inconvenient because they have to be held. In many instances, this can be difficult or impossible when the individual is carrying items, using electronics, or just relaxing.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Various aspects of the inventive concepts will be described more fully hereinafter with reference to the accompanying drawings, in which some exemplary embodiments are shown. The present inventive concept may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein.

It will be understood that, although the terms first, second, etc. are be used herein to describe various elements, these elements should not be limited by these terms. These terms are used to distinguish one element from another, but not to imply a required sequence of elements. For example, a first element can be termed a second element, and, similarly, a second element can be termed a first element, without departing from the scope of the present invention. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

It will be understood that when an element is referred to as being “on” or “connected” or “coupled” to another element, it can be directly on or connected or coupled to the other element or intervening elements can be present. In contrast, when an element is referred to as being “directly on” or “directly connected” or “directly coupled” to another element, there are no intervening elements present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.).

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises,” “comprising,” “includes” and/or “including,” when used herein, specify the presence of stated features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof.

Spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper” and the like may be used to describe an element and/or feature's relationship to another element(s) and/or feature(s) as, for example, illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use and/or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” and/or “beneath” other elements or features would then be oriented “above” the other elements or features. The device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

In accordance with aspects of the inventive concepts, provided is a wearable device, comprising. In various embodiments, the device includes a U-shaped housing, which has a first arm having a central first axis and a second arm having a central second axis, with the first and second arms being connected by an intermediate curved member.

FIG. 1 is a perspective view of a first embodiment of a wearable temperature control device, in accordance with aspects of inventive concepts. The wearable temperature control device can take the form of a wearable fan 100. FIG. 2 is a front view and FIG. 3 is a top view of the wearable fan 100. FIG. 4 is a bottom view and FIG. 5 is a rear view of the wearable fan 100. FIG. 6 is a right-side view and FIG. 7 is a left-side view of the wearable fan 100. FIG. 8 is an exploded view of the wearable fan 100. FIG. 9 is a front view of the wearable fan with intake vent caps removed. And FIG. 10 is a top view of the wearable fan with the intake vent caps removed.

The wearable fan 100 is U-shaped, being constructed and arranged to be worn around a user's neck. In other embodiments, a wearable fan could take a different form, e.g., to accommodate a different portion of the body or the neck, but just with a different shape. In some embodiments, the wearable fan 100 comprises a first arm 110, a second arm 160, and an intermediate member 150, which can be a curved member 150. The first arm 110 is coupled to a first end of the curved member 150? and the second arm 160 is coupled to a second end of the curved member 150.

In some embodiments, a first flexure 112 couples the first arm 110 to the curved member 150. In some embodiments, a second flexure 162 couples the second arm 160 to the curved member 150. The first 112 and/or second 162 flexures can be constructed and arranged to allow for adjustment or movement in the relative positions of the first arm 110 and the second arm 160 with respect to the curved member 150. In various embodiments, the movement of the first and second arms 110, 160 can be away from each other to create a greater space and opening between distal ends of the first and second arms, e.g., to accommodate the passing of a neck therethrough for wearing. To increase the space between the distal ends of the first and second arms, an outward force can be applied to one or both of the first and second arms 110, 160. In some embodiments, the first and second arms 110, 160 can move, bend, and/or flex in the same plane.

Accordingly, the first and second flexures 112, 162 can be structured to return the first and second arms to their original, neutral positions, once an applied force is removed, thereby narrowing the opening and space between the distal ends of the first and second arms 110, 160. Such narrowing can be useful for maintaining the wearable fan on the user's neck. In various embodiments, a width of the wearable fan is greatest between the distal ends of the first and second arms 110, 160 and the curved member 150.

The first flexure 112 can comprise one or more cutouts 113 constructed and arranged to facilitate movement or flexing of the first arm 110 with respect to the curved member 150. Similarly, the second flexure 162 can comprise one or more cutouts 163 constructed and arranged to facilitate movement or flexing of the second arm 160 with respect to the curved member 150. In some embodiments, the first and/or second flexures 112, 162 are constructed and arranged to allow for position adjustments or flexing of up to about 5 degrees of the arms 110, 160 with respect to the curved member 150, but the inventive concepts are not limited to such relative ranges of motion.

Therefore, in such embodiments, the first and second flexures 112, 162 can comprise one or more springs, such as an internal spring that biases the first and/or second arms back into their respective neutral positions. In some embodiments, the first and second flexures 112, 162 can be formed of a flexible material, such as thermoplastic polyurethane (TPU).
